DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

FIG. 1 is a block diagram illustrating an apparatus to which an exemplary embodiment of the present general inventive concept can be applied. As illustrated in FIG. 1, the apparatus is a digital camera including a lens unit 110, an image pick-up device 120, an image processing unit 130, an image outputting unit 140, a codec 150, a storage unit 160, a touch screen 170, and a control unit 180. The apparatus may be a computer mounted with a digital camera. In this case, at least one of the lens unit 110 and the image pickup unit 120 is disposed in the digital camera, and other units can be disposed in the computer.

The lens unit 110 collects light to allow an optical image to focus on an image pick-up region.

The image pick-up device 120 photoelectrically converts light incident through a lens into electrical signals and performs signal processing on the electrical signals. The image pick-up device 120 performing such a function includes an image sensor and an AD converter. The image sensor outputs image signals in analog form, and the AD convert converts and outputs the image signals in digital form.

The image processing unit 130 performs signal processing on images input from the image pick-up device 120 and transmits the processed image signals to display photographed images to the image outputting unit 140. The image processing unit 130 also outputs the processed image signals to the codec 150 in order to store the photographed images.

More specifically, the image processing unit 130 performs functions including digital zoom, auto white balance (AWB), auto focus (AF), and auto exposure (AE), etc., in order to control format conversion and image scaling of the image signals output from the image pick-up device 120.

The image outputting unit 140 outputs the image signals received from the image processing unit 130 to the touch screen 170, which may be an internal display apparatus or an external outputting terminal.

The codec 150 encodes the image signals received from the image processing unit 130, and transmits the encoded image signals to the storage unit 160. The codec 150 also decodes the encoded image signals stored in the storage unit 160, and transmits the decoded image signals to the image processing unit 130.

That is, the codec 150 encodes the image signals when storing the photographed image, and decodes the image signals when outputting the stored image to the image processing unit 130.

The storage unit 160 stores the photographed image in the image pick-up device 120 in a compressed form. The storage unit 160 may be a flash memory, a hard disk, a DVD, etc.

The touch screen 170 displays an image to be photographed, and receives a user's touch and transmits the input touch to the control unit 180.

The control unit 180 controls an entire operation of the photographing apparatus. More specifically, the control unit 180 controls the image processing unit 130 to perform signal processing on the photographed image. The control unit 180 also controls the codec 150 to encode or decode the image signals, generates a graphical user interface (GUI) and adds the generated GUI to an image to be displayed on the touch screen 170,

The controller 180 specifies a certain region of the image displayed on the touch screen 170 and controls a menu for the image displayed on the specified region (hereinafter, referred to as the ‘specified region menu’) to be displayed on the touch screen.

Herein, the specified region is a region selected in order to provide or emphasize certain effects. The control unit 180 determines the specified region based on position information on where a user touches the touch screen 170. However, the control unit 180 may determine the specified region to be a focused region or a region on which an image related to a particular photographic mode is displayed as well as the region to which a user's touch inputs,

The specified region menu is a menu to select effects for a portion of the image displayed on the specified region or effects for a portion of the image other than the portion displayed on the specified region. For example, the specified region menu may include items to make the portion of the image displayed on the specified region bright or dark, or to make the area around the portion of the image displayed on the specified region clear or dim.

The control unit 180 determines a type of image displayed on the specified region, and sets menu items for the specified region accordingly. The type of image may be, for example, an image of a person, an image of lights, or an image of a waterdrop, etc.

The image of the person refers to a portion of the image to be photographed on which a person is displayed. The person's characteristics are specified using the person's face. Therefore, in the image of the person, the person's face becomes the center.

The control unit 180 recognizes the person's face using facial recognition technology. Examples of the facial recognition technology include, but are not limited to, a color-based method, an edge-based method, and a support vector machine (SVM)-based method, etc. Detailed description of the facial recognition technology will be omitted.

The image of lights refers to a portion of the image to be photographed on which lights are displayed. The portion on which lights are displayed is brighter than a surrounding background. Therefore, the control unit 180 recognizes the image of lights using light recognition technology, which recognizes lights by recognizing a contrast ratio between a surrounding environment and an object. The control unit 180 determines the type of image displayed on the specified region using various other methods, and sets menu items for the specified region menu accordingly.

The specified region menu is a menu related to photographic techniques. The menu items of the specified region menu are displayed in user-friendly language. Herein, the user-friendly language refers to an expression describing effects on the image of using specific photographic techniques.

For example, when the menu item selected from the specified region menu is “lighter face”, a function of a corresponding item refers to a setting of photographic techniques to make a person's face brighter. Therefore, if a user selects a menu item “lighter face”, the control unit 180 slows the shutter speed and raises the exposure correction value in order that a face is brightly taken. That is, “lighter face” in use language corresponds to “slow shutter speed and raise exposure correction value” in technical language.

If the specified region menu is displayed in user-friendly language, the user can easily comprehend the functions of each item of the specified region menu, as described above.

Herein, the user selects an item from the specified region menu, the control unit 180 sets photographic techniques of a digital camera so that image effects corresponding to the selected menu item can be represented.

Herein, the photographic techniques refer to setting of the setting values of the camera to be set in order for the user to photograph his desired photo before he photographs the photo. The setting values related to photographic techniques include setting values such as aperture, shutter speed, exposure correction, color temperature, and focal length, etc. Besides, all setting values affecting an image to be photographed are included in the setting values related to the photographic techniques.

That is, if the user selects a menu item from the specified region menu, the control unit 180 controls the lens unit 110 or the image pick-up device 120 to illustrate effects of the selected menu item before an image is photographed.

The control unit 180 thus controls the specified region menu to be displayed before an image to be photographed is photographed.

When a touch is input on the touch screen 170, the control unit 180 controls the specified region menu to be displayed on the edge of the region where the touch is input.

When the type of image displayed on the specified region cannot be determined, the control unit 180 controls a menu for the entire displayed image to be displayed. For example, the control unit 180 may display a menu including items such as “brighter” and “darker” for the entire image.

Hereinafter, an operation of a digital camera will be described in detail with reference to FIGS. 1 and 2. FIG. 2 is a flow chart illustrating a method to provide a user interface to display a menu for an image on a specified region according to an exemplary embodiment of present general inventive concept.

A digital camera displays an image to be photographed on a touch screen 170 (operation S210). When a user touches the touch screen 170 (operation S220), the digital camera specifies a certain region of the displayed image centered on the touched position (operation S230). The digital camera determines a specified region based on position information where the user touches the touch screen 170. However, the digital camera may also determine the specified region to be a focused region and a region on which an image related to a photographic mode is displayed, as well as the region to which the user's touch is input.

A process to specify a region of the displayed image will be described in detail later with reference to FIGS. 4 to 8.

The digital camera subsequently determines the type of image included in the specified region (operation S240). The type of image may be, for example, an image of a person, an image of lights, or an image of waterdrop, etc.

When the image on the specified region is an image of a person (operation S250-Y), a menu related to photographic techniques for an image of a person is displayed (operation S255). For example, when the image on the specified region is an image of a person, the specified region menu includes menu items such as “lighter face”, “darker face”, “sharper background”, and “hazier background”. A screen illustrating the case when the image on the specified region is a person is illustrated in FIGS. 9 and 10.

When the image on the specified region is an image of lights (operation S260-Y), a menu related to photographic techniques related to images of lights is displayed (operation S265). For example, when the image on the specified region is an image of lights, the specified region menu includes items such as “warmer color”, “cooler color”, “dimmer light”, and “brighter light”. A screen illustrating the case when the image on the specified region is an image of lights is illustrated in FIGS. 11 and 12.

Meanwhile, when the image on the specified region is neither an image of a person nor a image of lights (operation S260-N), a menu related to photographic techniques of an entire image is displayed (operation S270). For example, the menu related to the photographic techniques for the entire image includes “lighter”, “darker”, “warmer color”, and “cooler color”. This feature is illustrated in FIG. 14.

The digital camera is able to provide the specified region menu through the process as described above.

Hereinafter, a specified region menu will be described in detail with reference to FIG. 3. FIG. 3 is a view illustrating a process to select a menu for an image on a specified region according to an exemplary embodiment of the present general inventive concept. FIG. 3 includes screen 3-1 310, screen 3-2 320, and screen 3-3 330.

Screen 3-1 310 illustrates a screen in which an image of a person image to be photographed is displayed on a touch screen 170 and a user touches a region on which a person's face is displayed. When the user touches the person's face, a specified region menu is displayed as illustrated in screen 3-2 320.

Screen 3-2 320 illustrates a screen on which a specified region menu 300 is displayed. The specified region menu 300 includes items such as “lighter face”, “darker face”, “sharper background”, and “hazier background”. As illustrated in screen 3-2 320, the specified region menu 300 is displayed above and below, and to the left and right of the position to which the user's touch is input. In this manner, since the specified region menu 300 is displayed on the edge of the position to which the user's touch is input, the user may intuitively know that the specified region menu 300 is a menu related to the image displayed on the touched position.

Also, the present embodiment describes the case in which the specified region menu 300 has four menu items, however, a number of menu items may vary. For example, FIG. 15 illustrates a case in which there are two menu items, FIG. 16 illustrates a case in which there are six menu items, FIG. 17 illustrates a case in which there are eight menu items.

Also, the present embodiment describes a case in which menu items of the specified region menu 300 are displayed as text in user-friendly language. However, the menu items may be implemented so that result images to which photographic techniques corresponding to the items of the specified region menu 300 are applied are displayed. A screen illustrating this feature is illustrated in FIG. 18.

Screen 3-3 330 illustrates a screen where a menu item 335 “lighter face” is selected from among the menu items of the specified region menu 300. A user touches a region on which the menu items of the specified region menu 300 are displayed, making selecting a desired menu item from the specified region menu 300 possible.

Also, the present embodiment describes a case where the menu items of the specified region menu 300 are selected using a touch screen. However, menu items may of course be selected using other operating techniques. For example, as illustrated in FIG. 19, the user may select the specified region menu 300 using a jog shuttle 1910.

In this case, the user specifies the desired region and selects menu items from the specified region menu 300, making selecting photographic techniques to have the desired effect on the desired region possible.
